I was driving my car and it lost power. It was still running, but would not go over 2000 rpm, safe mode?
I coaxed it to work, and when I tried to restart it, nothing. I have done ALL the normal no start stuff. but can't get it to crank and fire by the key. I have no wiring diagrams the show the start signal circuit.
As it sits, it will crank over with the relay jumped. Everything else works with the key on. The ECU scan tool says the clutch is depressed and the start signal is being received, based on the fact I can crank it with the jumped relay and it sill doesn't start I believe there is not fuel or spark. But since its not cranking but the ignition, I am not working on that issue, what ever is keeping it from cranking would keep the other things from coming on. I already replaced the ignition switch.
The ECU scan says the signals are going, I can hear some relays clicking, but I can verify which have power or not when (going to do that tomorrow).
Anyone have a wiring schematic of a 09+ aveo signal circuit? And the ign2 circuit which i believe turns on fuel and spark?
the other tech in the shop thinks the battery died and killed the ECU, i put in a junkyard ECU and no change. At this point he feels it is either the ECU program or a bad harness. Both are dealership trips and $$.
anyone have any other ideas?
